Guangzhou Xitang Electromechanical Technology Co., Ltd. was established in 2007 in the South China University of Technology Science Park. Xitang Technology focuses on packaging and material testing technology, dedicated to quality control in industries such as pharmaceuticals, food, packaging, textiles, and new materials. Its products are widely used in enterprises, testing institutions, universities, and research institutes. Xitang Technology, relying on South China University of Technology and Guangzhou Naval Academy, has three professors and associate professors, multiple doctoral and master's degrees, and over 95% of them have a college degree or above. They have won multiple first and second prizes in military scientific and technological progress in fields such as artillery and missile control, and naval combat software, and have collaborated with testing institutions to complete multiple research projects. Xitang Technology specializes in barrier testing, constant weight testing, and trace water detection technologies. The oxygen permeability test uses advanced dynamic leak detection technology, with an accuracy improved to 0.005 units; The balance protection technology realizes high-precision and stable weighing of precision balances in high temperature and high humidity environments, with a constant weight error of less than 0.3 mg; The electrolytic trace moisture sensor achieves ppb level accuracy; The laser infrared micro water sensor, in collaboration with the Chinese Academy of Sciences, has achieved an accuracy of 10 ppb. Xitang Technology is a high-tech enterprise. In the 2018 Entrepreneurship Competition, we won 7th place in the Guangzhou division and 18th place in the Guangdong province division. Precision originates from the process; Sincerity begins with small details.
